A model is presented taking into account off line-of-action, non linear wheel stiffness by using the finite element method, and elasticity coupling between the gear teeth. The contact points are determined by searching the common normal using the undeformed, but otherwise true theoretical, tooth shapes where the teeth have a tip rounding to prevent contact singularity in off-line-of-action points.

As custom architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-graph isomorphism and g

Popular Abstract in Swedish Människans utveckling och fysiologiska anpassning till upprätt kroppställning är beroende av en rad blodtrycksreglerande mekanismer. Vid ortostatisk hypotension sjunker blodtrycket i samband med uppresning från liggande till stående. Detta beror på en sviktande cirkulationsanpassning så att organismen inte förmår att upprätthålla ett tillräckligt högt blodtryck. SymtomeOrthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. Our findings in a large group of patients with Alzheimer's disease, vascular- and frontotem

We present a summary of the activities of the Multi-Jet final states and energy flows Working Group of the HERA and the LHC workshop, 2007-2008. Among the more specific topics considered were the status of and recent progress in higher order calculations, both in fixed perturbative expansions and in resummed approaches, recent progress in the description of jets, including the description of forwa

A matched filter composed of a time lagged feedforward artificial neural Network (TLFN) and a pulse-shaping filter is used in a noisy environment to detect R-waves for pacemakers. The TLFN reduces the influence of lower frequencies in the invasive electrogram (EGM) signals, e.g. P and T waves, and conditions the EGM to optimize the performance of the dynamically updated matched filter. Detector pe

Under år 1999 genomfördes en arkeologisk förundersökning i form av schaktningsövervakning i Södergatan, Skomakaregatan, Per Weijersgatan och Baltzarsgatan i Malmö stad under år 1999. Arbetena berörde Malmö äldre stadsområde, registrerat som fornlämning 20 i Malmö stad enligt Riksantikvarieämbetets fornminnesinformationssystem (FMIS). Sammanlagt övervakades 65 schakt, äldre lämningar påträffades i

Popular Abstract in Swedish Floran i ekplanteringar ? en effekt av miljö, spridning eller markhistoria? Bakgrund Europas befolkning ökande kraftigt efter industrialismens genombrott och som en följd av detta ökade behovet av åkermark för att försörja den växande skaran människor med mat. Mer och mer av den lövskog som tidigare täckte stora delar av norra Europa avverkades för att bli åkermark, In Europe, only small fragments of deciduous woodlands remain intact and species dependent on this ecosystem have declined. In southern Sweden, a shifting trend during the 20th century, with more afforestations on former arable land, resulted in new oak stands. These new stand are either on former arable fields or on continuously forested land. This thesis has its emphasis on colonization patterns

Popular Abstract in Swedish Hjärtkärlsjukdomar brukar definieras som ateriosklerotiska och tromboemboliska förändringar i hjärta, hjärna och i den arteriella blodcirkulationen. Dessa sjukdomar är mycket vanliga, och i Sverige insjuknar ca 40 000 personer i hjärtinfarkt och c 35 000 i hjärnblödning per år. Trots att det skett en sänkning av både incidens och dödlighet för dessa sjukdomar i västvärlThe Cardiovascular Risk Factor Study in Southern Sweden, CRISS, was initiated to explore if men at increased risk at developing CVD risk factors can be identified already before age 40. Starting in 1990 two birth cohorts of men residing in Helsingborg, Sweden, were surveyed at age 37 (n=991, participation rate 68%), at age 40 (n=770) and age 43 (n=702), respectively.
